Everyone can upvote their stuff, sure. I do sometimes to try to work my way up on a comment list to get the attention of an author or upvote my post as a minnow to try to stand out slightly on the new posts. However, I was only talking about self-upvoting to the other commenter.
Now seeing two comments self-upvoted 100% (which could've been just one edited comment), I'm left wondering why you wouldn't also share the rewards pool with the commenter who clearly supported you. The option is there and you can. That's the type of thought process that generally frustrates me - and I'm just venting when I see it. ...Someone upvoted your post, engaged me on your blog in your general defense, and you upvoted two of your replies, and not them.
No need to debate anything further. We've both made our points. I'm very curious about EOS and appreciate steps on how to buy it, but just had my opinion about pasting links in with referrals attached without explicitly mentioning it so people can be aware.
